MARTIN H. MANSFIELD, OF `ASHLAD, OHIO.

HANGER FOR SHAFTING.

Specicaton of Letters Patent No. 32,301, dated May 14, 1861.

To all whom it may concern:

Be it known that I, MARTIN I-I. MANs- FIELD, of Ashland, in the countyof Ashland and State of Ohio, have invented new and useful Improvementsin Journal-Boxes for Shafting of Threshing-Machines; and I do herebydeclare that the following isa full and complete description of theconstruction and operation of the same, reference being had to theaccompanying drawings, making part of this specification, in which-Figure' 1, is a perspective view. Fig. 2, is a top view, and Figs. 3 andI are sections.

Like letters refer'to like parts in the several views.

The nature of my invention relates to such a construction of journalboxes `that the shaft will always be in line, `the boxes themselvesbeing self adjusting in any direction. This self adjustment isespecially desirable in threshing machines, and others of a portablecharacter, and indeed, in any situation where an unequal pressure isfelt upon the shaft, by a belt or gear, near one of the boxes, thustending to wear one `of the boxes faster than the other, which wouldcause the journal to bind in the boxes, provided they were rigidlyfixed. i Vith my improvement, such a binding of the journals cannot takeplace, and this, in virtue of the "self-adjusting character of theboxes.`

The practical' advantages of my improvement is most` especially seen inthreshing and grain separating, and like machines. It is well known toevery one who has charge of such machines, that much care is required inthe adjustment of the boxes or bearings to the shaft, when the machinesare first put to work; and further,` by the very motion of the machinewhile at work, it is liable to get shifted in position and. in thismanner get the shafting out of line withV the journal boxes. But with myimprovement, allthese ,difficulties are obviated.

This improvement is also of great value upon Astreet rail roads,allowing a free adjustment of the axles in turning a curve.

A, A, are two metallic standards, rising from a base B. These'must be ofsuch size as to correspond to the size of the boxes and gearing to beused. Through the top of these, pass strong screws O, C, secured by ajam nut, D, that they may be kept securely in place. The ring E, issuspended and supported upon the points of these screws, which formpivots for the same, the v turn and revolve vertically upon the points iof these screw pivots, which pivots enter depressions in the horizontalsides of the ring and opposite'to each other.

F, F, represent two screws, also forming pivots, which pass through theupper and lower sides of the ring E, and which, are also furnished witham nuts, like those upon the screws C, and for"w the same object. Thesescrew pivots F, F, support the journal box G, by entering depressions onthe upper and lower sides thereof, thus allowing the box Gr, to turn ineither direction horizontally, and this arrangement allows of theadjustment of the box in any direction, either vertically by means ofthe ring E; horizontally by means of the pivots F, F, which support thejournal box-or obliquely, by the combined action of both ring and box,as set forth.

The box may be made as a pipe box, or it may be a divided box, and thetwo parts be secured-together by lugs and screw bolts in the usualmanner.

H, represents the horizontal shaft, leading from the motive power to theinclined shaft I, which connects with the machine. The shafts H and Iarejoined as is usual in such cases, and situations, by a universaljoint, J.

The base piece B, may be attach-ed to timbers K, K, and may lie upon theground in a rectangular form, as in Fig. l or as shown in Fig. 2.

What I claim as my improvement and desire to secure by Letters Patent,is-

The making of journal boxes, for shafting for threshing machines,adjustable; horizontally, vertically, and obliquely, by means of thestandards A, ringE, and screws C O and F F when arranged in relation tothe journal box G, as specified, thus givingit free motion in everydirection, as and for the purpose set forth.
